The Q36.5 Bullet Proof Base Layer redefines whats possible in extreme-cold performance apparel. Built for athletes and adventurers who face the harshest conditions, it delivers professional-grade warmth without the heavy, restrictive bulk of traditional insulation. Designed to fit seamlessly between a next-to-skin layer and an outer shell, it forms the critical middle tier of a three-layer thermal system, locking in heat while keeping weight to an absolute minimum.

At the heart of this breakthrough is Q36.5s proprietary Air Insulation technologyan ultralight, precision-brushed mesh that captures maximum air volume while dramatically increasing the surface area in contact with your body. Thousands of microscopic air pockets trap warmth close to the skin, while rapid moisture-wicking action keeps you dry and comfortable through high-intensity efforts. The result is unmatched thermal efficiency that adapts to fluctuating activity levels and weather conditions.

Engineered for unrestricted movement, the Bullet Proof Base Layer maintains an exceptionally low profile, allowing full mobility whether youre climbing alpine routes, charging down backcountry trails, or pushing through polar expeditions. Its resilient construction performs consistently after repeated wash cycles, ensuring long-term reliability for athletes who demand the best.

When brutal temperatures threaten to compromise performance, the Bullet Proof Base Layer proves that superior warmth doesnt have to mean added weight. Its the essential piece for anyone unwilling to sacrifice speed, agility, or comfort in the coldest environments.
